, 1 Claim. -1

The present invention relates to an improved floor drain and more particularly to a, floor drain in which the elevation and the angular disposition of the grate member may be adjusted relative to the sewer connection after the drain is connected with the sewer so that, the top surface of the grate may be accommodated to the level of the floor both as to elevation and angle.

In providing. drainsfor concrete floors, for example, it has. been the practice to install the sewer connections and floor drains prior to pouringthe concrete for the floor. Often, the level of the floor is not correct for the drain elevation, and the floor must be removed adjacent to the drain and the drain fixtures disconnected from the sewer and then reconnected at the proper level and the floor patched. This is expensive and the patching of the floor usually ruins its appearance as well as its waterproof properties if it possessed such.

An object of the present invention is to provide a floor drain fixture that has a body portion that is adapted to be attached to a sewer connection and having a grate member associated therewith, which may be easily adjusted to raise or lower the elevation thereof and to set the top surface at the proper angle with respect to the floor formed about the drain.

A further object of the invention is to provide a fioor drain fixture having means for adjustably positioning the grate, which means may be formed in the casting of certain parts of the drain and without machining or cutting operations, whereby the cost to produce the drain fixture is substantially the same as that of a nonadjustable fixture.

Other objects and advantages of the invention will be apparent from the followin description of one form of the invention, reference being made to the accompanying drawings wherein:

Fig. l is a top view in elevation of a floor drain fixture;

Fig, 2 is a View in section of the drain fixture, the view being taken on line 2-2 of Fig. 1; and

Fig. 3 is a view similar to that of Fig. 2, but showing the drain fixture in a cement floor with the grate member tilted relative to the level of the drain fixture.

Referring to the drawings, I have shown a floor drain fixture that illustrates one embodiment of the invention. The fixture comprises a bowllike body 5 that is open at the to for the reception of a sleeve-like collar member 6 that Company, Cleveland,

The outlet 1 is threaded internally for connecting the body with a sewer pipe, not shown, 10-.- cated beneath the surface of the floor, although the well known oakum and lead caulked con-' nection could be used instead of the threads shown. In the embodiment shown, a laterally extending flange 8 surrounds the body 5- for catching water that might seep intotthe floor. Weep holes 9 are formed in the body through which water passes vfrom the flange 8 into the body. A flat rin Hi lies in the flange 8, and bolts 12, threaded in clamps I3 held by lugs cast on the body, are: used for pressing the ring to the flange. This arrangement constitutes a clampin device for securing a lead or copper or membrane Waterproof sheathing M to the flange, which sheathing may extend beneath the floor surface some distance about the drain fixture for conveying seepage to the drain.

The collar 6 is recessed at l5 for receiving a slotted disc l6, that forms the grate for the top of the drain fixture. The collar 6 is adapted to fit relatively loosely in the body 5 so that it may be tilted or canted somewhat relative to the body as is shown in Fig. 3. The elevation of the collar 6 is adapted to be varied by causin it to be supported in the body by three similarly formed cams, two of which are shown at l9 and 20, and which are preferably in the form of flanges cast integral with the body 5. The cams each extend approximately one-third the way around the inside wall of the body in the form of a section of a spiral, as may be seen in the drawings. The lower edge of the collar 6 is shaped to conform with the cams, i. e., complementary thereto, so that by turning the collar one direction or the other, will cause the member to be cammed upwardly, as illustrated by the broken lines in Fig. 2, or downwardly with respect to the body. It will be noted that the cams do not extend inwardly beyond the wall of the collar so that they will not tend to retard the flow of water through the drain.

In installing the drain fixture in a concrete floor, the body 5 is connected with the sewer pipe before the concrete is poured and the collar is set midway between its fully extended and fully retracted positions and the floor is then poured. If the level of the floor should turn out to be above the grate top surface, before the concrete sets, the collar 6 may be extended upwardly by rotating it counter-clockwise, as viewed in Fig. 1, or if the door level should be below the grate surface, the grate is lowered by turning the collar in the opposite direction.

at 23, is vertical and the axis 24 of the body 5 is The chock 22 may comprise a relaoff vertical. tlvely short bar of metal, such as brass, and having a width substantially the same as the Width of flanges l9 and 20. r I

Thus, by my invention, a floor drain fixture is provided having an adjustable grate, the adjust-' ment mechanism being easily and inexpensively formed, and which provides adjustment of the elevation and the level of the grate surface.

Also, this form of adjustment permits the use or a relatively large grate and drain bowl so that the flow of drain water will be unrestricted' Although I have described but one form of embodiment of my invention, it is to be understood that other embodiments of the invention may be adopted, all falling within the scope of the claim which follows.

I claim:

An adjustable drain adapted to be set in concrete floors'comprising a tubular grat supporting member loosely telescoped within a cylindrlcal wall of a bowl-shaped drain pipe connecting member, the telescoping relationship of the two members being such that the grate supporting member is turnable relative to the bowl member and tiltable in any direction relative to the vertical center line of the bowl member, said bowl member having a stepped flange formation projecting inwardly from the cylindrical wall thereof to form lands for a complementary stepped formation comprising the lower edge of the grate supporting member whereby the top of the latter member may be disposed at a selected height, a chock block having a width substantially the width of the body flange and disposed at a selected position between the flange and lower edge of the grate supporting member, said bowl wall having an exteriorly disposed secondary drainage flan e intermediate the top and bottom of the bowl formation and the bowl wall having drainage passageways formed therein adjacent the top surface of the drainage flange and terminating within the bowl above the stepped flange.
